Zhang Laodao only suffered some abrasions, and after resting for a few days, he was fine. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info is also thanks to Sun Simiao's vigorous promotion, now I don't know the far places, and the Langzhong people near Chang'an also know that the things they use when saving people have been disinfected, and there are many infections caused by not paying attention to the treatment.

Zhang Laodao gave Xia Hongsheng some of the things he had left, because the stove blew up, overturning the Danfang, which was actually a grass shed that was transparent on all sides, so he lost a lot of things. However, Zhang Laodao patted his chest and promised that once the Danfang was repaired, he would be able to get it out again.

Xia Hongsheng took those things and tried them, and sure enough, it was as Zhang Laodao said.

Xia Hongsheng made a small artillery battle and tried it, although it only exploded a little, but the color of the firelight did change a little, which made Xia Hongsheng very happy, and felt that at least his thinking was right.

That night, Li Lizhi also said that Xia Hongsheng made such a big battle, just to make her happy, if Xu Hui knew, I was afraid that it would be inevitable to be sad, and I would have to make up for it. So this fireworks has to be made quickly, so that Xu Hui is also happy.

Xia Hongsheng then made a few two kicks, rolled the gunpowder with hard paper, divided into two layers in the middle, the particles below were larger and burned slowly, and the bottom was sealed with soil, so that the explosion of the lower layer rose into the air as a thrust, and the upper layer exploded again. In the upper layer of gunpowder, mixed with the powder found by Zhang Laodao, it can have different colors after exploding.

This is the prototype of Xia Hongsheng's attempt to make fireworks, and he has only made four of the remaining powder from Zhang Laodao, and he has put one to try, and there are still a few left.

It was dark, and Xia Hongsheng took the two kickers to the academy.

As soon as he walked to the office, he saw Xu Qixian about to raise his hand and knock on the door, turned his head and saw Xia Hongsheng, and came over to salute: "Students meet the mountain chief!" ”

"Uh, let's go inside." Xia Hongsheng was a little unaccustomed to Xu Qixian calling him a mountain chief, so he opened the door and entered the house and let Xu Qixian go in as well.

"What's wrong, Brother Xu, what's the matter with me?" After entering the house, there were only two people left after closing the door, Xia Hongsheng asked.

Xu Qixian sat down and asked Xia Hongsheng: "Senior brother, I heard that our academy made that hot air balloon, you flew into the palace and flew in front of Princess Changle, and made Princess Changle cry with excitement?" ”

Xia Hongsheng listened to Xu Qixian's sour tone, first stunned, and then suddenly annoyed: "Li Ke told you? ”

"No, it was Li Tai who said it." Xu Qixian shook his head and said.

Xia Hongsheng listened, hey, this little bastard! After Li Ke came back on time, he told Li Tai, and Li Tai deliberately said that he would listen to Xu Qixian and give his sister a long face!

"This, Hui'er doesn't know, right?" Xia Hongsheng asked.

Xu Qixian shook his head: "I don't know." ”

"Uh, Brother Xu, this thing is indeed actually made for Princess Changle." Xia Hongsheng confessed frankly and said, "I have prepared a unique thing for the princess and Hui'er and gave it to them as a gift. The hot air balloon is the one for Li Li. ”

"You also prepared one for Hui'er?" Xu Qixian's tone was still sour: "Alas, poor my sister misses someone at home all day long......"

"Uh...... Brother Xu, look at what you said. Xia Hongsheng scratched his head and said, "Naturally, I also prepared a gift for Hui'er." It's just that there are a few things missing in it, so I haven't made a finished product yet, and only a few prototypes have been made. ”

As he spoke, Xia Hongsheng took out the second kicks and said, "Look! ”

"That's it!" Xu Qixian was suddenly a little unconvinced: "This can be compared to that hot air balloon?!" ”

"Don't, Brother Xu, you don't know, if this thing is finally made, it will not be inferior to the hot air balloon." Xia Hongsheng hurriedly explained to Xu Qixian: "If this thing is made into a finished product, then you can enjoy the seven-colored light and rain in the sky, and the world is like a fairyland!" ”

Xu Qixian was stunned: "Seven-colored light rain? What's that? ”

"Let's go, I'll show you!" Xia Hongsheng took the three second kicks and said to Xu Qixian.

Originally, Xia Hongsheng took this thing to the academy to try it out for an interview in the academy, so that the students could see and be curious, and by the way, they could feel the magic of Gewu. Moreover, when the time comes, you can also use the name of the academy and say that this thing made by the academy is the same as a hot air balloon, which is produced by Jingyang Academy.

It just so happened that Xu Qixian knew about Li Liqian, and he was upset for his sister, and Xia Hongsheng also happened to let him take an Anxin pill in advance.

Why do you sound like such a scumbag?

Xia Hongsheng responded to himself in his heart.

took Xu Qixian to the square at the back, and it was the busiest time on campus at night. People without classes walk here, gather and discuss, play badminton and table tennis......

Change Ming'er to get a few more sports activities, Xia Hongsheng thought about it for a while, erect a basketball hoop and level a football field, volleyball, baseball, and rugby! Do some more gym equipment out?

While thinking, he searched for a place where there were fewer people, and then put things on the ground.

Some students around saw Xia Hongsheng putting things on the ground, so they immediately came over.

"Look at the sidelines, don't get close, don't get close, be careful of danger." Xia Hongsheng said to the students around him, so that more people will come over.

Xia Hongsheng looked at Xu Qixian and said in a low voice: "These are only semi-finished products, they are used for experiments, and the finished products are countless times better than this!" ”

After speaking, Xia Hongsheng glanced at Qi Yong.

Since the lighter was made, Qi Yong has been very fond of setting off cannons, and he likes to set off bombs the most, but unfortunately he doesn't, so he likes to set off firecrackers instead.

Qi Yong took out the fire fold, blew hard, blew out a few sparks, and then leaned over.

I saw Qi Yong bend down and bring the fire fold closer, and then he heard three consecutive sounds of "bang bang bang".

"Look at the sky!" Xia Hongsheng shouted.

Everyone subconsciously raised their heads, and before Xia Hongsheng's words fell, they suddenly heard three loud noises from the sky, the difference is that this time the three loud noises, accompanied by three different colors of light, exploded in the night sky. At night, three colors of light appeared on it at the same time, and it was very beautiful.

"What's going on?" Xia Hongsheng looked at Xu Qixian and said, "At that time, there will be more than three, and there will be more than three colors." When the finished product came out, it was a sky full of seven-colored flashes scattered like rain, endless, and definitely no worse than a hot air balloon! ”

Xu Qixian was very excited: "Okay! That's good! Hehe, this, the student is ashamed...... If you need the help of your students, just take your words and make the finished product as soon as possible! ”
